2000 Zoning
Critics of Portland's UGB have suggested that Clark County, Washington, has absorbed much of the sprawl that might have otherwise occurred in Oregon. Land use maps and air photography confirm this suggestion, however, development has come mainly in the form of large lot rural residential sites, not in proliferation of subdivisions (Map 6). Our study site was selected to capture the edge of suburban expansion north of Vancouver, Washington, in an area that included both urban and rural zoning. Most of the area zoned urban is large lot rural residential, not subdivisions, and much of the area zoned rural is in 1-20 acre parcels interspersed with farms, not unlike the Happy Valley study area.
